Stuck on Mimiron

A friend and I were going through Ulduar ok until we hit Mimiron.

I'am Demonology and my friend is a fire Mage so dps for this isnt a problem.

Everything was great until we hit phase 4 where everything comes together, we couldnt stop him from repairing so therefore we couldnt get him down.
I read somewhere you have to get all 3 pieces down within 10 seconds, pretty sure we did that but no he still repaired.

Neither of us have gotten that far before in Ulduar and a lot of the online strats are raid ones.

If he is repairing that means you dont dps all 3 of his body parts down at the same or close to same time. Unless its bugged, though a friend solo'd him 2 nights ago so im thinking the first thing is your problem.

He has 3 body parts
Head
Body
Feet

Some people dont notice the head when i run pugs.

I play many games. WoW, Rift, D3, PoE, SC2 I will not criticize your game choice if you don't mine.

Did it 2 nights ago with a friend, the fight wasn't bugged to us. If you have the DBM-Wotlk mods running you should see the 3 healthframes of the 3 parts.
Indeed get them down together as said before. If you are both level 90, that should be no problem at all. You probably just missed one part.

Thanks guys, we're just too slow I guess.
We'll nail it tomorrow.
I do have DBM up but didnt see the parts.
Only Yogg and General Vezax to go after this one, anything we should look out for?
Going for the Astral title.

After a bit of research your right, we only need to knock over Algalon for the title.
From what I read it was confusing, it said Algalon is a Heroic mode boss only but yet his available in 10 and 25 man runs.
So can we get the title running as a 2 man team doing 10 man or do we have to change it to 25 man?
I'd rather knock over 8.3 million hp's compared to 35 million.

It USED to be that you had to do the 4 keepers on hard mode in order to get the key to do algalon, but they have removed the key and the time restraint from algalon so now you just need to kill flame levi and deconstructor to get to him. After decon if you hang a right in the next room (opposite side from iron council) there's a door to open and he is on the other side of it.

I solo Ulduar 10 frequently. When I do Mimiron I always play Affliction and in final phase I just keep dots rolling on all 3 parts. If there is a part not being damaged as fast as the others I just throw on a haunt for that piece, refresh dots and focus a bit more on the other two by cycling drain life (not MG).

Algalon isn't soloable, and while his melee damage isn't too bad, the phase punch debuff means you need 2 tanks. I'm not sure if pets avoid it. I'd hazard not as it's not an AOE ability. He hits fast and although I said his melee damage isn't too bad at 90, it will add up. I wouldn't even try to push 25 man with just 2 people.
